Mesoscale Discussion 0036

Areas affected...Portions of central AL and
west-central/northwestern GA

Concerning...Tornado Watch 4...

Valid 260758Z - 260930Z

The severe weather threat for Tornado Watch 4 continues.

SUMMARY...An isolated severe threat may persist for a couple more
hours early this morning before gradually diminishing. A couple
tornadoes and occasional strong/gusty winds should be the main
threats.

DISCUSSION...Recent radar imagery shows a broken line of storms
extending northeast to southwest across northwestern GA and central
AL. The low-level flow across this region should have a tendency to
gradually veer to a more southwesterly direction and slowly weaken
as the strongest portion of a low-level jet advances into the
Carolinas over the next few hours. Even so, there should still be
enough veering/strengthening of the wind field in low levels
(reference 06Z BMX sounding) to support updraft rotation. A couple
tornadoes will remain possible in the short term with storms
advancing northeastward within the broken line. Isolated
strong/gusty winds producing occasional damage may also occur with
any cell that can acquire a small bowing structure. Current
expectations are for this isolated severe threat to gradually
diminish later this morning as the low-level flow becomes
increasingly parallel to the ongoing convection, which should reduce
0-1 km SRH. The marginal thermodynamic environment across
west-central into northern GA should also limit the eastward extent
of any meaningful severe risk.
